Claims18
A latching mechanism for sealing an access panel to an adjacent sidewall, comprising:
- a cam rod pivotable between a first position and a second position, the cam rod including a handle and at least one generally U-shaped bend, wherein when the cam rod is in the first position, the cam rod is arranged at an angle to the access panel and a portion of the U-shaped bend is configured to engage a surface of the access panel;
- and
- a latch mounted to the access panel and rotatable between a third position and a fourth position, wherein the latch is configured to engage and apply a force to the handle when in the fourth position.
A method for sealing an access panel to an adjacent sidewall comprising:
- pivoting the access panel to a closed position;
- rotating a cam rod having a handle and at least one generally U-shaped bend from a first position to a second position, wherein in the second position, the cam rod is arranged at an angle to the access panel such that a portion of the at least one U-shaped bend is configured to contact a surface of the access panel;
- rotating a latch from a third position to a fourth position, wherein in the fourth position the latch engages the handle of the cam rod and applies a force thereto.
The method according to claim 18, wherein the handle is formed by from a U-shaped bend having sidewalls longer than the remainder of the plurality of U-shaped bends.
